Hi Guys
NGC6337 Cheerio Nebula in colour mapped narrowband.
Ha:OIII:SII Ha 2rs:OIII and SII 1 hr: all 900sec subs at bin 1, mapped as RGB.
This one is really small and dim. Image capture was a big mistake, I spent too much time with 3nm Ha hoping to use it as lum, its mostly OIII.
Proccessing planetary nebs is a random experience, in this case Ha as lum was a shocker, hence the RGB only processing, they are all quite different, and its hard to know which pallet/processing to use with so few examples on the web, and relative signal strength is only obvious once capture is done.
AO was working at 4hz, but high wind shows with slightly dodgy guiding.
Its a bit technicolour, but since I cant get close to Hubble, its hopeless trying to guess whats best, so I just went for pretty

.
Oh for 20", 16meg/95%QE, dark skies and 5m FL
